The only Ernie from Youngstown that I know personally who was connected to the Pittsburgh rackets was Ernest "Ernie B" Biondillo, who was shotgunned to death on orders from Youngstown crime boss Lenny Strollo on June 3rd, 1996. Ernie would have been 23 years old at the time of the Mannarino wedding. Very Interesting Maggie, thanks for sharing.
